411's are kinda deep for a 3 speed auto. I would try 355's or at the most 373's

P.S. I was assuming you had an auto. trans. If you have a 4 speed I would go with the 373's. A good all around gear.

I would be looking at the exhaust system (if stock). The stock heads are also going to frustrate you more with those 3.55 gears - you will run out of RPM quickly because they do not flow well.
These rubber bumper cars can run as well as the older chrome bumper cars but you have to chage some stuff to make them work like they should.

You will definitely notice an improvement, but as previously stated, I wouldn't go higher than a 3.70 gear as highway driving becomes very loud and proud. 3.55 is a safe choice for the best of both worlds.
